there have been major heating and cooling periods .... much longer than 50 years.... and there are many other explanations that could and should be explored than that AGW has occurred. There is nothing scientific about jumping to conclusions. Yes there are facts but any idiot can understand plain English usually. Facts are not in question here but what are the CAUSES are. That simple enough even for you? You seem to be the anti-science person around here. You act as though your favorite website is the gospel. Its not. Try reading something other than the "bible" you kept promoting and that website. A few loose ends???? ummm hmmmm......
